My 2 cents:

I treat accessibility as a subset of usability. Usability is about ensuring our design and development is effective and efficient. Accessibility is about ensuring our design and development is effective and efficient for individuals with disabilities.

Issues that apply to all users should be categorized under usability.
Those that apply for disabled users (for example many of the issues covered by WCAG) fall into the accessibility category.

Note that as a subset of usability, all accessibility issues are usability issues.

Hello all, Greetings!

How I should differentiate between usability bugs and accessibility bugs?
Really confused when I want to categorize bugs into these zones. What are
the checkpoints to keep in mind on a whole while deciding a bug as
usability or accessibility?

Need your valuable expertise.

Thanks,
